Meshed WiFi with QCA9377 (USB/SDIO)

More RED bean testing:

I have changed hardware now, from:

Dell E6430 (O2 Micro, Inc. OZ600FJ0/OZ900FJ0/OZ600FJS SD/MMC Card Reader Controller (rev 05))

to

Dell Latitude 7480 (Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev 01))

This solves the issue:

mmc0: Internal clock never stabilised.

But instead, with the latest "master", I get:

Wrt firmware, we actually have 4 different versions to choose between, any 
recommendation?

The kvalo/ath10k one looks promising, but comes without board file. Are 
there dependencies between the firmware versions and the board files, or 
can we just grab a board file from github.com/8devices and use that one 
with the firmware from kvalo/ath10k-firmware?
